You can not add links from CSS, you will have to do so from the HTML code explicitly. For example, something like this:
<a href="whatever.html"><li id="header"></li></a>
As most people have pointed out that subclassing UITableViewCell
solves this issue.
But the reason this not allowed because the prototype cell(UITableViewCell) is defined by Apple and you cannot add any of your own outlets to it.
GDB Dashboard
https://github.com/cyrus-and/gdb-dashboard
This GDB configuration uses the official GDB Python API to show us whatever we want whenever GDB stops after for example next
, much like TUI.
However I have found that this implementation is a more robust and configurable alternative to the built-in GDB TUI mode as explained at: gdb split view with code
For example, we can configure GDB Dashboard to show disassembly, source, registers and stack with:
dashboard -layout source assembly registers stack
Here is what it looks like if you enable all available views instead:

It is important to keep in mind that let is lazy evaluated and not putting side-effect methods in it otherwise you would not be able to change from let to before(:each) easily. You can use let! instead of let so that it is evaluated before each scenario.
Try this:
var div = document.getElementsByClassName('drill_cursor')[0];
div.addEventListener('click', function (event) {
alert('Hi!');
});
Examine error log (start eventvwr.msc). MySQL typically writes something to the Application log.
In very rare cases it does not write anything (I'm only aware of one particular bug http://bugs.mysql.com/bug.php?id=56821, where services did not work at all). There is also error log file, normally named .err in the data directory that has the same info as written to windows error log.
To format an Instant
a time-zone is required. Without a time-zone, the formatter does not know how to convert the instant to human date-time fields, and therefore throws an exception.
The time-zone can be added directly to the formatter using withZone()
.
DateTimeFormatter formatter =
DateTimeFormatter.ofLocalizedDateTime( FormatStyle.SHORT )
.withLocale( Locale.UK )
.withZone( ZoneId.systemDefault() );
If you specifically want an ISO-8601 format with no explicit time-zone (as the OP asked), with the time-zone implicitly UTC, you need
DateTimeFormatter.ISO_LOCAL_DATE_TIME.withZone(ZoneId.from(ZoneOffset.UTC))
Now use that formatter to generate the String representation of your Instant.
Instant instant = Instant.now();
String output = formatter.format( instant );
Dump to console.
System.out.println("formatter: " + formatter + " with zone: " + formatter.getZone() + " and Locale: " + formatter.getLocale() );
System.out.println("instant: " + instant );
System.out.println("output: " + output );
When run.
formatter: Localized(SHORT,SHORT) with zone: US/Pacific and Locale: en_GB
instant: 2015-06-02T21:34:33.616Z
output: 02/06/15 14:34

If you have installed mongodb community server via homebrew, then you can do:
brew services list
This will list the current services as below:
Name Status User Plist
mongodb-community started thehaystacker /Users/thehaystacker/Library/LaunchAgents/homebrew.mxcl.mongodb-community.plist
redis stopped
Then you can restart mongodb by first stopping and restart:
brew services stop mongodb
brew services start mongodb
JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

According Angular documentation:
createEmbeddedView
Instantiates an embedded view and inserts it into this container.
abstract createEmbeddedView(templateRef: TemplateRef, context?: C, index?: number): EmbeddedViewRef
.Param Type Description templateRef TemplateRef the HTML template that defines the view. context C optional. Default is undefined. index number the 0-based index at which to insert the new view into this container. If not specified, appends the new view as the last entry.
When angular creates template by calling createEmbeddedView it can also pass context that will be used inside ng-template
.
Using context optional parameter, you may use it in the component, extracting it within the template just as you would with the *ngFor.
app.component.html:
<p *for="number; let i=index; let c=length; let f=first; let l=last; let e=even; let o=odd">
item : {{i}} / {{c}}
<b>
{{f ? "First,": ""}}
{{l? "Last,": ""}}
{{e? "Even." : ""}}
{{o? "Odd." : ""}}
</b>
</p>
for.directive.ts:
import { Directive, Input, TemplateRef, ViewContainerRef } from '@angular/core';
class Context {
constructor(public index: number, public length: number) { }
get even(): boolean { return this.index % 2 === 0; }
get odd(): boolean { return this.index % 2 === 1; }
get first(): boolean { return this.index === 0; }
get last(): boolean { return this.index === this.length - 1; }
}
@Directive({
selector: '[for]'
})
export class ForDirective {
constructor(private templateRef: TemplateRef<any>, private viewContainer: ViewContainerRef) { }
@Input('for') set loop(num: number) {
for (var i = 0; i < num; i++)
this.viewContainer.createEmbeddedView(this.templateRef, new Context(i, num));
}
}
What about casting to Number in Javascript using the Unary (+) Operator
lat: 12.23

Depends on the use case. Here is a fullchart what works and what not: parseInt vs unary plus - when to use which
A ternary will suffice. change:
gotdata = dlist[1]
to
gotdata = dlist[1] if len(dlist) > 1 else 'null'
this is a shorter way of expressing
if len(dlist) > 1:
gotdata = dlist[1]
else:

You can check for a module's installation path by:
perldoc -l XML::Simple
The problem with your one-liner is that, it is not recursively traversing directories/sub-directories. Hence, you get only pragmatic module names as output.
In getting started with require.js I ran into the issue and as a beginner the docs may as well been written in greek.
The issue I ran into was that most of the beginner examples use "anonymous defines" when you should be using a "string id".
anonymous defines
define(function() {
return { helloWorld: function() { console.log('hello world!') } };
})
define(function() {
return { helloWorld2: function() { console.log('hello world again!') } };
})
define with string id
define('moduleOne',function() {
return { helloWorld: function() { console.log('hello world!') } };
})
define('moduleTwo', function() {
return { helloWorld2: function() { console.log('hello world again!') } };
})
When you use define with a string id then you will avoid this error when you try to use the modules like so:
require([ "moduleOne", "moduleTwo" ], function(moduleOne, moduleTwo) {
moduleOne.helloWorld();
moduleTwo.helloWorld2();
});
May be the private key itself is not present in the file.I was also faced the same issue but the problem is that there is no private key present in the file.
<input type="text" ng-keypress="checkNumeric($event)"/>
//inside controller
$scope.dot = false
$scope.checkNumeric = function($event){
if(String.fromCharCode($event.keyCode) == "." && !$scope.dot){
$scope.dot = true
}
else if( isNaN(String.fromCharCode($event.keyCode))){
$event.preventDefault();
}
Its unbelievable after so many answers, but I did it little differently in the end. I don't like primary key to be nullable, I want to have it as first argument and also want to insert without defining it and also it should not be var.
@Entity(tableName = "employments")
data class Employment(
@PrimaryKey(autoGenerate = true) val id: Long,
@ColumnInfo(name = "code") val code: String,
@ColumnInfo(name = "title") val name: String
){
constructor(code: String, name: String) : this(0, code, name)
}
You probably need to use STR_TO_DATE function:
select * from hockey_stats
where
game_date between STR_TO_DATE('11/3/2012 00:00:00', '%c/%e/%Y %H:%i:%s')
and STR_TO_DATE('11/5/2012 23:59:00', '%c/%e/%Y %H:%i:%s')
order by game_date desc;
(if game_date is a string, you might need to use STR_TO_DATE on it)
Update
Chrome changed how to inspect requests and suggests now to use the Catapult Netlog Viewer with the logs exported from chrome://net-export/
chrome://net-export/
Old Chrome Versions
You also may use this link in Chrome for more detailed information than the inspector did it.
chrome://net-internals/#events
This shows the log of all requests of the browser while open
I used to do this a lot when I worked with Classic ASP. Usually I used it when server-side validation was needed of some sort for the input (before the days of AJAX). The main draw back I see is that it doesn't separate programming logic from the presentation, at the file level.
The problem is on this line:
oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"
Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:
oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "
You also have a typo in S:Claims\Sound.wav
, should be S:\Claims\Sound.wav
.
I also assume the apostrophe before Dim oShell
and after Set oShell = Nothing
are typos as well.

I found the easiest approach is to use the Distinct Count
option under Value Field Settings
(left click the field in the Values
pane). The option for Distinct Count
is at the very bottom of the list.
Here are the before (TOP; normal Count
) and after (BOTTOM; Distinct Count
)
Just adding a parameter like the below worked for me.
cursor=conn.cursor(dictionary=True)
I hope this would be helpful either.
Here's how I got it working:
In AppDelegate.swift
inside the didFinishLaunchingWithOptions
function I put:
NotificationCenter.default.addObserver(self, selector: #selector(AppDelegate.rotated), name: UIDevice.orientationDidChangeNotification, object: nil)
and then inside the AppDelegate class I put the following function:
func rotated() {
if UIDeviceOrientationIsLandscape(UIDevice.current.orientation) {
print("Landscape")
}
if UIDeviceOrientationIsPortrait(UIDevice.current.orientation) {
print("Portrait")
}
}
Hope this helps anyone else!
Thanks!

In your apps.js just add
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
Now you can use ejs view engine while keeping your view files as .html
source: http://www.makebetterthings.com/node-js/how-to-use-html-with-express-node-js/
You need to install this two packages:
`npm install ejs --save`
`npm install path --save`
And then import needed packages:
`var path = require('path');`
This way you can save your views as .html instead of .ejs.
Pretty helpful while working with IDEs that support html but dont recognize ejs.
Using UIPickerview is the right way to go to implement it according to Apple's Human Interface Guidelines
If you select drop down in mobile safari it will show UIPickerview to let the use choose drop down items.
Alternatively
you can use UIPopoverController till iOS 9 as its deprecated but its better to stick with UIModalPresentationPopover of view you want o show as well
you can use UIActionsheet to show the items but it's better to use UIAlertViewController and choose UIActionSheetstyle to show as the former is deprecated in latest versions
Unfortunately there is no hung state for a process. Now hung can be deadlock. This is block state. The threads in the process are blocked. The other things could be live lock where the process is running but doing the same thing again and again. This process is in running state. So as you can see there is no definite hung state. As suggested you can use the top command to see if the process is using 100% CPU or lot of memory.
Here is a sample script that I recently used in a Gateway POST transaction that receives a GET response. Are you using this in a custom C# form? Whatever your purpose, just replace the String fields (username, password, etc.) with the parameters from your form.
private String readHtmlPage(string url)
{
//setup some variables
String username = "demo";
String password = "password";
String firstname = "John";
String lastname = "Smith";
//setup some variables end
String result = "";
String strPost = "username="+username+"&password="+password+"&firstname="+firstname+"&lastname="+lastname;
StreamWriter myWriter = null;
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";
try
{
myWriter = new StreamWriter(objRequest.GetRequestStream());
myWriter.Write(strPost);
}
catch (Exception e)
{
return e.Message;
}
finally {
myWriter.Close();
}
HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
using (StreamReader sr =
new StreamReader(objResponse.GetResponseStream()) )
{
result = sr.ReadToEnd();
// Close and clean up the StreamReader
sr.Close();
}
return result;
}
Note that GCC has an extension to the designated initializer notation which is very useful for the context. It is also allowed by clang
without comment (in part because it tries to be compatible with GCC).
The extension notation allows you to use ...
to designate a range of elements to be initialized with the following value. For example:
#include <stdio.h>
enum { ROW = 5, COLUMN = 10 };
int array[ROW][COLUMN] = { [0 ... ROW-1] = { [0 ... COLUMN-1] = 1 } };
int main(void)
{
for (int i = 0; i < ROW; i++)
{
for (int j = 0; j < COLUMN; j++)
printf("%2d", array[i][j]);
putchar('\n');
}
return 0;
}
The output is, unsurprisingly:
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
Note that Fortran 66 (Fortran IV) had repeat counts for initializers for arrays; it's always struck me as odd that C didn't get them when designated initializers were added to the language. And Pascal uses the 0..9
notation to designate the range from 0 to 9 inclusive, but C doesn't use ..
as a token, so it is not surprising that was not used.
Note that the spaces around the ...
notation are essentially mandatory; if they're attached to numbers, then the number is interpreted as a floating point number. For example, 0...9
would be tokenized as 0.
, .
, .9
, and floating point numbers aren't allowed as array subscripts.
With the named constants, ...ROW-1
would not cause trouble, but it is better to get into the safe habits.
Addenda:
I note in passing that GCC 7.3.0 rejects:
int array[ROW][COLUMN] = { [0 ... ROW-1] = { [0 ... COLUMN-1] = { 1 } } };
where there's an extra set of braces around the scalar initializer 1
(error: braces around scalar initializer [-Werror]
). I'm not sure that's correct given that you can normally specify braces around a scalar in int a = { 1 };
, which is explicitly allowed by the standard. I'm not certain it's incorrect, either.
I also wonder if a better notation would be [0]...[9]
— that is unambiguous, cannot be confused with any other valid syntax, and avoids confusion with floating point numbers.
int array[ROW][COLUMN] = { [0]...[4] = { [0]...[9] = 1 } };
Maybe the standards committee would consider that?
Maybe the above methods work... I tried some and didn't for me. What did was this :
Run this in terminal :
/usr/libexec/java_home
If you write your code in emacs then you might be interested in the htmlize elisp package.

Another way is to handle the CellContentClick event (which doesn't give you the current value in the cell's Value property), call grid.CommitEdit(DataGridViewDataErrorContexts.Commit) to update the value which in turn will fire CellValueChanged where you can then get the actual (i.e. correct) DataGridViewCheckBoxColumn value.
private void grid_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
grid.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
private void grid_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
// do something with grid.Rows[e.RowIndex].Cells[e.ColumnIndex].Value
}
Target .NET framework: 2.0
It's a hexadecimal number.
0x6400 translates to 4*16^2 + 6*16^3 = 25600
it's because the name of the submit button is named "submit", change it to anything but "submit", try "submitme" and retry it. It should then work.
=VLOOKUP(LARGE(A1:A10,ROW()),A1:B10,2,0)
Type this formula in first row of your sheet then drag down till fifth row...
its a simple vlookup
, which finds the large
value in array (A1:A10)
, the ROW()
function gives the row number (first row = 1, second row =2 and so on) and further is the lookup criteria.
Note: You can replace the ROW()
to 1,2,3,4,5 as requried...if you have this formula in other than the 1st row, then make sure you subtract some numbers from the row()
to get accurate results.
EDIT: TO check tie results
This is possible, you need to add a helper column to the sheet, here is the link. Do let me know in case things seems to be messy....
select top 10 * from
(
select distinct p.id, ....
)
will work.
dt=$(date --date yesterday "+%a %d/%m/%Y")
echo $dt
So Soumyaansh's Revo Uninstaller Pro fix worked for me :) ( After 2 days of troubleshooting other options {screams internally 😀} ).
I did run into the an issue with his method though, "Could not find a suitable SDK to target" even though I selected to install Visual Studio with custom settings and selected the SDK I wanted to install. You may need to download the Windows 10 Standalone SDK to resolved this, in order to develop UWP apps if you see this same error after reinstalling Visual Studio.
To do this
Windows 10 SDK (WINDOWS_VERSION_NUMBER_HERE)
-> Windows 10 SDK (14393) etc . . .). If there are no SDKs on your system go to step 2!format
supports a percentage floating point precision type:
>>> print "{0:.0%}".format(1./3)
33%
If you don't want integer division, you can import Python3's division from __future__
:
>>> from __future__ import division
>>> 1 / 3
0.3333333333333333
# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%
# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%
The answer is correct, however the perl documentation on how to handle deadlocks is a bit sparse and perhaps confusing with PrintError, RaiseError and HandleError options. It seems that rather than going with HandleError, use on Print and Raise and then use something like Try:Tiny to wrap your code and check for errors. The below code gives an example where the db code is inside a while loop that will re-execute an errored sql statement every 3 seconds. The catch block gets $_ which is the specific err message. I pass this to a handler function "dbi_err_handler" which checks $_ against a host of errors and returns 1 if the code should continue (thereby breaking the loop) or 0 if its a deadlock and should be retried...
$sth = $dbh->prepare($strsql);
my $db_res=0;
while($db_res==0)
{
$db_res=1;
try{$sth->execute($param1,$param2);}
catch
{
print "caught $_ in insertion to hd_item_upc for upc $upc\n";
$db_res=dbi_err_handler($_);
if($db_res==0){sleep 3;}
}
}
dbi_err_handler should have at least the following:
sub dbi_err_handler
{
my($message) = @_;
if($message=~ m/DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction/)
{
$caught=1;
$retval=0; # we'll check this value and sleep/re-execute if necessary
}
return $retval;
}
You should include other errors you wish to handle and set $retval depending on whether you'd like to re-execute or continue..
Hope this helps someone -
If I understand the question correctly, you simply want to "undo" the git add
that was done for that file.
If you need to remove a single file from the staging area, use
git reset HEAD -- <file>
If you need to remove a whole directory (folder) from the staging area, use
git reset HEAD -- <directoryName>
Your modifications will be kept. When you run git status
the file will once again show up as modified but not yet staged.
See the git reset
man page for details.
One way of doing it:
df[, colSums(is.na(df)) != nrow(df)]
If the count of NAs in a column is equal to the number of rows, it must be entirely NA.
Or similarly
df[colSums(!is.na(df)) > 0]
IsEmpty()
would be the quickest way to check for that.
IsNull()
would seem like a similar solution, but keep in mind Null has to be assigned to the cell; it's not inherently created in the cell.
Also, you can check the cell by:
count()
counta()
Len(range("BCell").Value) = 0
Make sure to download these from here:
Also create PATH
enviroment variable on you computer like this (if it doesn't exist already):
PATH
variable doesn't exist among "User variables" click New
(Variable name: PATH, Variable value : C:\Program Files\Java\jdk1.8.0\bin;
<-- please check out the right version, this may differ as Oracle keeps updating Java). ;
in the end enables assignment of multiple values to PATH
variable.To be sure that everything works, open CMD Prompt and type: java -version
to check for Java version and javac
to be sure that compiler responds.
I hope this helps. Good luck!
If you want to do it the way the calculator actually does it, use the Babylonian technique. It is explained here and here.
Suppose you want to calculate the square root of 2:
a=2
a1 = (a/2)+1
b1 = a/a1
aminus1 = a1
bminus1 = b1
while (aminus1-bminus1 > 0):
an = 0.5 * (aminus1 + bminus1)
bn = a / an
aminus1 = an
bminus1 = bn
print(an,bn,an-bn)
This worked for me :
body {
font-size: calc([minimum size] + ([maximum size] - [minimum size]) * ((100vw - [minimum
viewport width]) / ([maximum viewport width] - [minimum viewport width])));
}
Explained in detail here: https://css-tricks.com/books/volume-i/scale-typography-screen-size/
I believe Spring Boot supports loading properties maps out of the box with @ConfigurationProperties annotation.
According that docs you can load properties:
my.servers[0]=dev.bar.com
my.servers[1]=foo.bar.com
into bean like this:
@ConfigurationProperties(prefix="my")
public class Config {
private List<String> servers = new ArrayList<String>();
public List<String> getServers() {
return this.servers;
}
}
I used @ConfigurationProperties feature before, but without loading into map. You need to use @EnableConfigurationProperties annotation to enable this feature.
Cool stuff about this feature is that you can validate your properties.
You can also remove all the git related stuff using one command. The .gitignore file will also be deleted with this one.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.
You can try this sample code:
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" android:id="@+id/rootLayout">
<Button
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MOVE" android:layout_centerHorizontal="true"/>
<ImageView
android:id="@+id/img1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
<ImageView
android:id="@+id/img2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
<ImageView
android:id="@+id/img3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">
<ImageView
android:id="@+id/img4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
</LinearLayout>
</RelativeLayout>
Your activity
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
{
@Override
public void onClick(View v)
{
ImageView img = (ImageView) findViewById( R.id.img1 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img2 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img3 );
moveViewToScreenCenter( img );
img = (ImageView) findViewById( R.id.img4 );
moveViewToScreenCenter( img );
}
});
}
private void moveViewToScreenCenter( View view )
{
RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
DisplayMetrics dm = new DisplayMetrics();
this.getWindowManager().getDefaultDisplay().getMetrics( dm );
int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();
int originalPos[] = new int[2];
view.getLocationOnScreen( originalPos );
int xDest = dm.widthPixels/2;
xDest -= (view.getMeasuredWidth()/2);
int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;
TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
anim.setDuration(1000);
anim.setFillAfter( true );
view.startAnimation(anim);
}
The method moveViewToScreenCenter
gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset
variable measures the status bar height.
I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.
Upsides: enums can have any values you like in any order you like and it's still easy to iterate over them. Names and values are defined once, in the first #define.
Downsides: if you use this at work, you need a whole paragraph to explain it to your coworkers. And, it's annoying to have to declare memory to give your loop something to iterate over, but I don't know of a workaround that doesn't confine you to enums with adjacent values (and if the enum will always have adjacent values, the enum might not be buying you all that much anyway.)
//create a, b, c, d as 0, 5, 6, 7
#define LIST x(a) x(b,=5) x(c) x(d)
#define x(n, ...) n __VA_ARGS__,
enum MyEnum {LIST}; //define the enum
#undef x //needed
#define x(n,...) n ,
MyEnum myWalkableEnum[] {LIST}; //define an iterable list of enum values
#undef x //neatness
int main()
{
std::cout << d;
for (auto z : myWalkableEnum)
std::cout << z;
}
//outputs 70567
The trick of declaring a list with an undefined macro wrapper, and then defining the wrapper differently in various situations, has a lot of applications other than this one.
It seems however that splitting in the middle of the values of a for loop doesn't need a caret(and actually trying to use one will be considered a syntax error). For example,
for %n in (hello
bye) do echo %n
Note that no space is even needed after hello or before bye.
It should suffice to say whether bcrypt or SHA-512 (in the context of an appropriate algorithm like PBKDF2) is good enough. And the answer is yes, either algorithm is secure enough that a breach will occur through an implementation flaw, not cryptanalysis.
If you insist on knowing which is "better", SHA-512 has had in-depth reviews by NIST and others. It's good, but flaws have been recognized that, while not exploitable now, have led to the the SHA-3 competition for new hash algorithms. Also, keep in mind that the study of hash algorithms is "newer" than that of ciphers, and cryptographers are still learning about them.
Even though bcrypt as a whole hasn't had as much scrutiny as Blowfish itself, I believe that being based on a cipher with a well-understood structure gives it some inherent security that hash-based authentication lacks. Also, it is easier to use common GPUs as a tool for attacking SHA-2–based hashes; because of its memory requirements, optimizing bcrypt requires more specialized hardware like FPGA with some on-board RAM.
Note: bcrypt is an algorithm that uses Blowfish internally. It is not an encryption algorithm itself. It is used to irreversibly obscure passwords, just as hash functions are used to do a "one-way hash".
Cryptographic hash algorithms are designed to be impossible to reverse. In other words, given only the output of a hash function, it should take "forever" to find a message that will produce the same hash output. In fact, it should be computationally infeasible to find any two messages that produce the same hash value. Unlike a cipher, hash functions aren't parameterized with a key; the same input will always produce the same output.
If someone provides a password that hashes to the value stored in the password table, they are authenticated. In particular, because of the irreversibility of the hash function, it's assumed that the user isn't an attacker that got hold of the hash and reversed it to find a working password.
Now consider bcrypt. It uses Blowfish to encrypt a magic string, using a key "derived" from the password. Later, when a user enters a password, the key is derived again, and if the ciphertext produced by encrypting with that key matches the stored ciphertext, the user is authenticated. The ciphertext is stored in the "password" table, but the derived key is never stored.
In order to break the cryptography here, an attacker would have to recover the key from the ciphertext. This is called a "known-plaintext" attack, since the attack knows the magic string that has been encrypted, but not the key used. Blowfish has been studied extensively, and no attacks are yet known that would allow an attacker to find the key with a single known plaintext.
So, just like irreversible algorithms based cryptographic digests, bcrypt produces an irreversible output, from a password, salt, and cost factor. Its strength lies in Blowfish's resistance to known plaintext attacks, which is analogous to a "first pre-image attack" on a digest algorithm. Since it can be used in place of a hash algorithm to protect passwords, bcrypt is confusingly referred to as a "hash" algorithm itself.
Assuming that rainbow tables have been thwarted by proper use of salt, any truly irreversible function reduces the attacker to trial-and-error. And the rate that the attacker can make trials is determined by the speed of that irreversible "hash" algorithm. If a single iteration of a hash function is used, an attacker can make millions of trials per second using equipment that costs on the order of $1000, testing all passwords up to 8 characters long in a few months.
If however, the digest output is "fed back" thousands of times, it will take hundreds of years to test the same set of passwords on that hardware. Bcrypt achieves the same "key strengthening" effect by iterating inside its key derivation routine, and a proper hash-based method like PBKDF2 does the same thing; in this respect, the two methods are similar.
So, my recommendation of bcrypt stems from the assumptions 1) that a Blowfish has had a similar level of scrutiny as the SHA-2 family of hash functions, and 2) that cryptanalytic methods for ciphers are better developed than those for hash functions.
Using the provided IntentInegrator is better. It allows you to prompt your user to install the barcode scanner if they do not have it. It also allows you to customize the messages. The IntentIntegrator.REQUEST_CODE constant holds the value of the request code for the onActivityResult to check for in the above if block.
IntentIntegrator intentIntegrator = new IntentIntegrator(this); // where this is activity
intentIntegrator.initiateScan(IntentIntegrator.ALL_CODE_TYPES); // or QR_CODE_TYPES if you need to scan QR

Source Negated Regular Expressions in location
Explanation of Regex :
If URL does not match any of the following path

As of JDK6U18 following are configurations for the Heap Size.
In the Client JVM, the default Java heap configuration has been modified to improve the performance of today's rich client applications. Initial and maximum heap sizes are larger and settings related to generational garbage collection are better tuned.
The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte. For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes. The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. This amount is at least 8 megabytes and otherwise 1/64 of physical memory up to a physical memory size of 1 gigabyte.

You can also make your objects Serializable and use the Bundle's getSerializable and putSerializable methods.
The following should work fine:
git diff -z --name-only commit1 commit2 | xargs -0 -IREPLACE rsync -aR REPLACE /home/changes/protected/
To explain further:
The -z
to with git diff --name-only
means to output the list of files separated with NUL bytes instead of newlines, just in case your filenames have unusual characters in them.
The -0
to xargs
says to interpret standard input as a NUL-separated list of parameters.
The -IREPLACE
is needed since by default xargs
would append the parameters to the end of the rsync
command. Instead, that says to put them where the later REPLACE
is. (That's a nice tip from this Server Fault answer.)
The -a
parameter to rsync
means to preserve permissions, ownership, etc. if possible. The -R
means to use the full relative path when creating the files in the destination.
Update: if you have an old version of xargs
, you'll need to use the -i
option instead of -I
. (The former is deprecated in later versions of findutils
.)

just use the core https module with the https.request function. Example for a POST
request (GET
would be similar):
var https = require('https');
var options = {

path: '/upload',
method: 'POST'
};
var req = https.request(options, function(res) {
console.log('STATUS: ' + res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log('BODY: ' + chunk);
});
});
req.on('error', function(e) {
console.log('problem with request: ' + e.message);
});
// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

By code:
btn_edit.IsEnabled = true;
By XAML:
<Button Content="Edit data" Grid.Column="1" Name="btn_edit" Grid.Row="1" IsEnabled="False" />
Well ya you can do that in this way.
<input type="text" name="address" id="address">
<div id="map_canvas" style="width: 500px; height: 300px"></div>
<input type="button" onclick="showAddress(address.value)" value="ShowMap"/>
Java Script
function showAddress(address){
alert("This is address :"+address)
}
That is one example for the same. and that will run.
There are basically 4 types of main constraints in SQL:
Domain Constraint: if one of the attribute values provided for a new tuple is not of the specified attribute domain
Key Constraint: if the value of a key attribute in a new tuple already exists in another tuple in the relation
Referential Integrity: if a foreign key value in a new tuple references a primary key value that does not exist in the referenced relation
Entity Integrity: if the primary key value is null in a new tuple
Try to declare these functions as extern "C++"
if your compiler supports this, http://msdn.microsoft.com/en-us/library/s6y4zxec(VS.80).aspx
Ensure that not exists already (artifact and version) in nexus (as release). In that case return Bad Request.

Assuming that you've written an equals method for Dog correctly that compares based on the id of the Dog the easiest and simplest way to return an item in the list is as follows.
if (dogList.contains(dog)) {
return dogList.get(dogList.indexOf(dog));
}
That's less performance intensive that other approaches here. You don't need a loop at all in this case. Hope this helps.
P.S You can use Apache Commons Lang to write a simple equals method for Dog as follows:
@Override
public boolean equals(Object obj) {
EqualsBuilder builder = new EqualsBuilder().append(this.getId(), obj.getId());
return builder.isEquals();
}
I'd have put this in as a comment as I'm really not certain that this is likely to be the case, but as I recall it doesn't a try/except statement involve a modification to the way the garbage disposal mechanism of the compiler works, in that it clears up object memory allocations in a recursive way off the stack. There may not be an object to be cleared up in this case or the for loop may constitute a closure that the garbage collection mechanism recognises sufficient to enforce a different collection method. Probably not, but I thought it worth a mention as I hadn't seen it discussed anywhere else.
An ASP.NET HTTP
handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file
, the request is processed by the page via the page handler.
The ASP.NET page handler is only one type of handler. ASP.NET comes with several other built-in handlers such as the Web service handler for .asmx files
.
You can create custom HTTP handlers when you want special handling that you can identify using file name extensions in your application. For example, the following scenarios would be good uses of custom HTTP handlers:
RSS feeds To create an RSS feed for a site, you can create a handler that emits RSS-formatted XML. You can then bind the .rss extension (for example) in your application to the custom handler. When users send a request to your site that ends in .rss, ASP.NET will call your handler to process the request.
Image server If you want your Web application to serve images in a variety of sizes, you can write a custom handler to resize images and then send them back to the user as the handler's response.
HTTP handlers have access to the application context, including the requesting user's identity (if known), application state, and session information. When an HTTP handler is requested, ASP.NET calls the ProcessRequest
method on the appropriate handler. The handler's ProcessRequest
method creates a response, which is sent back to the requesting browser. As with any page request, the response goes through any HTTP modules that have subscribed to events that occur after the handler has run.
To use the array type properly as a function argument or template parameter, make a struct instead of a typedef, then add an operator[]
to the struct so you can keep the array like functionality like so:
typedef struct type24 {
char& operator[](int i) { return byte[i]; }
char byte[3];
} type24;
type24 x;
x[2] = 'r';
char c = x[2];
The first step is figuring out what the error actually is. In order to do this expand your MsBuild output to be diagnostic. This will reveal the actual command executed and hopefully the full error message as well
Use whatever service manager your system offers - for example under Ubuntu use upstart. This will handle all the details for you such as start on boot, restart on crash, etc.
I use printf, is shorter as it doesn't need flags to do the work:

I am a beginner to screen but I find it immensely useful while restoring lost connections. Your question has already been answered but this information might serve as an add on - I use putty with putty connection manager and name my screens - "tab1", "tab2", etc. - as for me the overall picture of the 8-10 tabs is more important than each individual tab name. I use the 8th tab for connecting to db, the 7th for viewing logs, etc. So when I want to reattach my screens I have written a simple wrapper which says:
#!/bin/bash
screen -d -r tab$1
where first argument is the tab number.
// the index of each item in fieldNames must correspond to
// the correct index in resultItems
var fieldnames = new []{"itemtype", "etc etc "};
for (int e = 0; e < fieldNames.Length - 1; e++)
{
newRecord
.GetType()
.GetProperty(fieldNames[e])
.SetValue(newRecord, resultItems[e]);
}
I know this is a wicked old post with a whole lot of answers but a lot of people think that they NEED to either break things apart and put them back together or they insist that there's no way to implicitly do the conversion the OP original asked for.
To review and to hopefully provide an easy answer to others with the same question, the OP asked how to convert '10/15/2008 10:06:32 PM' to a DATETIME. Now, SQL Server does have some language dependencies for temporal conversions but if the language is english or something similar, this becomes a simple problem... just do the conversion and don't worry about the format. For example (and you can use CONVERT or CAST)...
SELECT UsingCONVERT = CONVERT(DATETIME,'10/15/2008 10:06:32 PM')
,UsingCAST = CAST('10/15/2008 10:06:32 PM' AS DATETIME)
;
... and that produces the follow answers, both of which are correct.
Like they say on the TV commercials, "But wait! Don't order yet! For no extra cost, it can do MUCH more!"
Let's see the real power of temporal conversions with the DATETIME and partially examine the mistake known as DATETIME2. Check out the whacky formats that DATETIME can handle auto-magically and that DATETIME2 cannot. Run the following code and see...
--===== Set the language for this example.

So, yeah... SQL Server DOES actually have a pretty flexible method of handling all sorts of weird-o temporal formats and no special handling is required. We didn't even need to remove the "PM"s that were added to the 24 hour times. It's "PFM" (Pure Freakin' Magic).
Things will vary a bit depending on the the LANGUAGE is that you've selected for your server but a whole lot of it will be handled either way.
And these "auto-magic" conversions aren't something new. They go a real long way back.
This is one way to accomplish this using PowerShell:
<#
.SYNOPSIS
Restores (applies) a previously saved stash based on full or partial stash name.
.DESCRIPTION
Restores (applies) a previously saved stash based on full or partial stash name and then optionally drops the stash. Can be used regardless of whether "git stash save" was done or just "git stash". If no stash matches a message is given. If multiple stashes match a message is given along with matching stash info.
.PARAMETER message
A full or partial stash message name (see right side output of "git stash list"). Can also be "@stash{N}" where N is 0 based stash index.
.PARAMETER drop
If -drop is specified, the matching stash is dropped after being applied.
.EXAMPLE
Restore-Stash "Readme change"
Apply-Stash MyStashName
Apply-Stash MyStashName -drop
Apply-Stash "stash@{0}"
#>
function Restore-Stash {
[CmdletBinding()]
[Alias("Apply-Stash")]
PARAM (
[Parameter(Mandatory=$true)] $message,
[switch]$drop
)
$stashId = $null
if ($message -match "stash@{") {
$stashId = $message
}
if (!$stashId) {
$matches = git stash list | Where-Object { $_ -match $message }
if (!$matches) {
Write-Warning "No stashes found with message matching '$message' - check git stash list"
return
}
if ($matches.Count -gt 1) {
Write-Warning "Found $($matches.Count) matches for '$message'. Refine message or pass 'stash{@N}' to this function or git stash apply"
return $matches
}
$parts = $matches -split ':'
$stashId = $parts[0]
}
git stash apply ''$stashId''
if ($drop) {
git stash drop ''$stashId''
}
}
Checked the evironment path, I have two paths navigated to two pip.exe and this caused this error. After deleting the redundant one and restart the PC, this issue has been fixed. The same issue for the jupyter command fixed as well.
I use the following vba code to determine the entire used rows range for the worksheet to then shorten the selected range of a column:
Set rUsedRowRange = Selection.Worksheet.UsedRange.Columns( _
Selection.Column - Selection.Worksheet.UsedRange.Column + 1)
Also works the other way around:
Set rUsedColumnRange = Selection.Worksheet.UsedRange.Rows( _
Selection.Row - Selection.Worksheet.UsedRange.Row + 1)
If your input always has a time zone of "zulu" ("Z" = UTC), then you can use DateTimeFormatter.ISO_INSTANT
(implicitly):
final Instant parsed = Instant.parse(dateTime);
If time zone varies and has the form of "+01:00" or "+01:00:00" (when not "Z"), then you can use DateTimeFormatter.ISO_OFFSET_DATE_TIME
:
DateTimeFormatter formatter = DateTimeFormatter.ISO_OFFSET_DATE_TIME;
final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter);
If neither is the case, you can construct a DateTimeFormatter
in the same manner as DateTimeFormatter.ISO_OFFSET_DATE_TIME
is constructed.
Your current pattern has several problems:
ResolverStyle.STRICT
);yyyy
instead of uuuu
(yyyy
will not work in strict mode);hh
instead of 24-hour HH
;S
for fractional seconds, but input has three.With LINQ, you could use the SkipWhile
/ TakeWhile
methods, like this:
var importantLines =
File.ReadLines(pathToTextFile)
.SkipWhile(line => !line.Contains("CustomerEN"))
.TakeWhile(line => !line.Contains("CustomerCh"));
If you want to use each of the lines of the file as command-line params for your application you can use the xargs command.
xargs -a <params_file> <command>
A params file with:
a
b
c
d
and the file tr.py:
import sys
print sys.argv
The execution of
xargs -a params ./tr.py
gives the result:
['./tr.py', 'a', 'b', 'c', 'd']
If you create your gems with bundler:
# do this in the proper directory
bundle gem foobar
You can install them with rake after they are written:
# cd into your gem directory
rake install
Chances are, that your downloaded gem will know rake install
, too.
With this method Integer.toHexString, you can have an Unknown color exception for some colors when using Color.parseColor.
And with this method String.format("#%06X", (0xFFFFFF & intColor)), you'll lose alpha value.
So I recommend this method:
public static String ColorToHex(int color) {
int alpha = android.graphics.Color.alpha(color);
int blue = android.graphics.Color.blue(color);
int green = android.graphics.Color.green(color);
int red = android.graphics.Color.red(color);
String alphaHex = To00Hex(alpha);
String blueHex = To00Hex(blue);
String greenHex = To00Hex(green);
String redHex = To00Hex(red);
// hexBinary value: aabbggrr
StringBuilder str = new StringBuilder("#");
str.append(alphaHex);
str.append(blueHex);
str.append(greenHex);
str.append(redHex );
return str.toString();
}
private static String To00Hex(int value) {
String hex = "00".concat(Integer.toHexString(value));
return hex.substring(hex.length()-2, hex.length());
}
You can use strtotime() for time calculation. Here is an example:
$checkTime = strtotime('09:00:59');
echo 'Check Time : '.date('H:i:s', $checkTime);
echo '<hr>';
$loginTime = strtotime('09:01:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!'; echo '<br>';
echo 'Time diff in sec: '.abs($diff);
echo '<hr>';
$loginTime = strtotime('09:00:59');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';
echo '<hr>';
$loginTime = strtotime('09:00:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';
Check the already-asked question - how to get time difference in minutes:
Subtract the past-most one from the future-most one and divide by 60.
Times are done in unix format so they're just a big number showing the number of seconds from January 1 1970 00:00:00 GMT
Compromise minimum solution:
| One | Two | Three | Four | Five | Six

| Span <td colspan=3>triple <td colspan=2>double
So you can omit closing </td>
for speed, ?r can leave for consistency.

As of 2019 year all pipes in the second line are compulsory in Jupyter Markdown.

In addition to the nested approach above, you can accomplish the application of theLIMIT
using JOIN
on the same table:
UPDATE `table_name`
INNER JOIN (SELECT `id` from `table_name` order by `id` limit 0,100) as t2 using (`id`)
SET `name` = 'test'
In my experience the mysql query optimizer is happier with this structure.
Array has no indexOf()
method.
Maybe this Apache Commons Lang ArrayUtils
method is what you are looking for
import org.apache.commons.lang3.ArrayUtils;
String[] colours = { "Red", "Orange", "Yellow", "Green" };
int indexOfYellow = ArrayUtils.indexOf(colours, "Yellow");
Callback from service to activity to update UI.
ResultReceiver receiver = new ResultReceiver(new Handler()) {

instructionServiceIntent.putExtra("receiver", receiver);
context.startService(instructionServiceIntent);
sqsh (http://www.sqsh.org/) + freetds (http://www.freetds.org)
sqsh was primarily an isql replacement for Sybase SQL Server (now ASE) but it works just fine for connecting to SQL Server (provided you use freetds).
To compile, simply point $SYBASE to freetds install and it should work from there. I use it on my Mac all day.
The best part of sqsh are the advanced features, such as dead simple server linking (no need to set up linked servers in SQL Server), flow control and looping (no more concatenating strings and executing dynamic SQL), and invisible bulk copy/load.
Anyone who uses any other command line tool is simply crazy! :)
"
would work in this particular case, as suggested before me, because of the HTML context.
However, if you want your JavaScript code to be independently escaped for any context, you could opt for the native JavaScript encoding:
'
becomes \x27
"
becomes \x22
So your onclick would become:DoEdit('Preliminary Assessment \x22Mini\x22');
This would work for example also when passing a JavaScript string as a parameter to another JavaScript method (alert()
is an easy test method for this).
I am referring you to the duplicate Stack Overflow question, How do I escape a string inside JavaScript code inside an onClick handler?.
Add the following to the top of your file # coding=utf-8
If you go to the link in the error you can seen the reason why:
Defining the Encoding
Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

Service hangs up at WaitForExit after calling batch file
It's about a question as to why a service can't execute a file, but it shows all the code necessary to do so.
In case of a range
or any other linearly increasing array you can simply calculate the index programmatically, no need to actually iterate over the array at all:
def first_index_calculate_range_like(val, arr):
if len(arr) == 0:
raise ValueError('no value greater than {}'.format(val))
elif len(arr) == 1:
if arr[0] > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
first_value = arr[0]
step = arr[1] - first_value
# For linearly decreasing arrays or constant arrays we only need to check
# the first element, because if that does not satisfy the condition
# no other element will.
if step <= 0:
if first_value > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
calculated_position = (val - first_value) / step
if calculated_position < 0:
return 0
elif calculated_position > len(arr) - 1:
raise ValueError('no value greater than {}'.format(val))
return int(calculated_position) + 1
One could probably improve that a bit. I have made sure it works correctly for a few sample arrays and values but that doesn't mean there couldn't be mistakes in there, especially considering that it uses floats...
>>> import numpy as np
>>> first_index_calculate_range_like(5, np.arange(-10, 10))
16
>>> np.arange(-10, 10)[16] # double check
6
>>> first_index_calculate_range_like(4.8, np.arange(-10, 10))
15
Given that it can calculate the position without any iteration it will be constant time (O(1)
) and can probably beat all other mentioned approaches. However it requires a constant step in the array, otherwise it will produce wrong results.
A more general approach would be using a numba function:
@nb.njit
def first_index_numba(val, arr):
for idx in range(len(arr)):
if arr[idx] > val:
return idx
return -1
That will work for any array but it has to iterate over the array, so in the average case it will be O(n)
:
>>> first_index_numba(4.8, np.arange(-10, 10))
15
>>> first_index_numba(5, np.arange(-10, 10))
16
Even though Nico Schlömer already provided some benchmarks I thought it might be useful to include my new solutions and to test for different "values".
The test setup:
import numpy as np
import math
import numba as nb
def first_index_using_argmax(val, arr):
return np.argmax(arr > val)
def first_index_using_where(val, arr):
return np.where(arr > val)[0][0]
def first_index_using_nonzero(val, arr):
return np.nonzero(arr > val)[0][0]
def first_index_using_searchsorted(val, arr):
return np.searchsorted(arr, val) + 1
def first_index_using_min(val, arr):
return np.min(np.where(arr > val))
def first_index_calculate_range_like(val, arr):
if len(arr) == 0:
raise ValueError('empty array')
elif len(arr) == 1:
if arr[0] > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
first_value = arr[0]
step = arr[1] - first_value
if step <= 0:
if first_value > val:
return 0
else:
raise ValueError('no value greater than {}'.format(val))
calculated_position = (val - first_value) / step
if calculated_position < 0:
return 0
elif calculated_position > len(arr) - 1:
raise ValueError('no value greater than {}'.format(val))
return int(calculated_position) + 1
@nb.njit
def first_index_numba(val, arr):
for idx in range(len(arr)):
if arr[idx] > val:
return idx
return -1
funcs = [
first_index_using_argmax,
first_index_using_min,
first_index_using_nonzero,
first_index_calculate_range_like,
first_index_numba,
first_index_using_searchsorted,
first_index_using_where
]
from simple_benchmark import benchmark, MultiArgument
and the plots were generated using:
%matplotlib notebook
b.plot()
b = benchmark(
funcs,
{2**i: MultiArgument([0, np.arange(2**i)]) for i in range(2, 20)},
argument_name="array size")
The numba function performs best followed by the calculate-function and the searchsorted function. The other solutions perform much worse.
b = benchmark(
funcs,
{2**i: MultiArgument([2**i-2, np.arange(2**i)]) for i in range(2, 20)},
argument_name="array size")
For small arrays the numba function performs amazingly fast, however for bigger arrays it's outperformed by the calculate-function and the searchsorted function.
b = benchmark(
funcs,
{2**i: MultiArgument([np.sqrt(2**i), np.arange(2**i)]) for i in range(2, 20)},
argument_name="array size")
This is more interesting. Again numba and the calculate function perform great, however this is actually triggering the worst case of searchsorted which really doesn't work well in this case.
Another interesting point is how these function behave if there is no value whose index should be returned:
arr = np.ones(100)
value = 2
for func in funcs:
print(func.__name__)
try:
print('-->', func(value, arr))
except Exception as e:
print('-->', e)
With this result:
first_index_using_argmax
--> 0
first_index_using_min
--> zero-size array to reduction operation minimum which has no identity
first_index_using_nonzero
--> index 0 is out of bounds for axis 0 with size 0
first_index_calculate_range_like
--> no value greater than 2
first_index_numba
--> -1
first_index_using_searchsorted
--> 101
first_index_using_where
--> index 0 is out of bounds for axis 0 with size 0
Searchsorted, argmax, and numba simply return a wrong value. However searchsorted
and numba
return an index that is not a valid index for the array.
The functions where
, min
, nonzero
and calculate
throw an exception. However only the exception for calculate
actually says anything helpful.
That means one actually has to wrap these calls in an appropriate wrapper function that catches exceptions or invalid return values and handle appropriately, at least if you aren't sure if the value could be in the array.
Note: The calculate and searchsorted
options only work in special conditions. The "calculate" function requires a constant step and the searchsorted requires the array to be sorted. So these could be useful in the right circumstances but aren't general solutions for this problem. In case you're dealing with sorted Python lists you might want to take a look at the bisect module instead of using Numpys searchsorted.

Let's keep it simple. Loved @digitaldreamer 's answer but it might leave the beginners confused. So, I am going to try and simplify it.
The only HTML comment is <!-- -->
It can be used as a single line comment or double, it is really up to the developer.
So, an HTML comment starts with <!--
and ends with -->
. It is really that simple. You should not use any other format, to avoid any compatibility issue even if the comment format is legit or not.
I know this is an old question, but gracchus's solution doesn't work if file names contain spaces. VonC's solution to file names with spaces is to not remove them utilizing --ignore-unmatch
, then remove them manually, but this will not work well if there are a lot.
Here is a solution that utilizes bash arrays to capture all files.
# Build bash array of the file names
while read -r file; do
rmlist+=( "$file" )
done < <(git ls-files -i --exclude-standard)
git rm –-cached "${rmlist[@]}"
git commit -m 'ignore update'
I solved this error in pom.xml by adding the below code
spring-rest-demo org.apache.maven.plugins maven-war-plugin 2.6From the docs:
str.split([sep[, maxsplit]])
Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most
maxsplit+1
elements).
s.split('mango', 1)[1]
I had the same problem after upgrading from .NET 4.5 to .NET 4.5.1. What fixed it for me was running this command:
netsh winsock reset
It all depends on the data at hand. If you have considerable amount of data then 80/20 is a good choice as mentioned above. But if you do not Cross-Validation with a 50/50 split might help you a lot more and prevent you from creating a model over-fitting your training data.
IOC is a concept which is implemented by two ways. Dependency creation and dependency injection, Factory/Abstract factory are the example of dependency creation. Dependency injection is constructor, setter and interface. The core of IOC is to not depend upon the concrete classes, but define the abstract of methods(say an Interface/abstract class) and use that abstract to call method of concrete class. Like Factory pattern return the base class or interface. Similariliy dependency injection use base class/interface to set value for objects.
Two other possible solutions:
Kill TSVNCache.exe and let it re-launch. This has caused my shell overlay icons to re-appear on several occasions.
If you've recently upgraded TortoiseSVN from a previous version, you may need to upgrade your working copy. This can be done by right-clicking on your project folder and choose "SVN Upgrade working copy" from the context menu.
If you are at a certain branch mybranch
, just go ahead and git checkout commit_hash
. Then you can return to your branch by git checkout mybranch
. I had the same game bisecting a bug today :) Also, you should know about git bisect.

In reply to Dimitrys answer but using Ajax.BeginForm
the following works at least with MVC >5 (4 not tested).
write a model as shown in the other answers,
In the "parent view" you will probably use a table to show the data.
Model should be an ienumerable. I assume, the model has an id
-property. Howeverm below the template, a placeholder for the modal and corresponding javascript
<table>
@foreach (var item in Model)
{
<tr> <td id="[email protected]">
@Html.Partial("dataRowView", item)
</td> </tr>
}
</table>
<div class="modal fade" id="editor-container" tabindex="-1"
role="dialog" aria-labelledby="editor-title">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content" id="editor-content-container"></div>
</div>
</div>
<script type="text/javascript">
$(function () {
$('.editor-container').click(function () {
var url = "/area/controller/MyEditAction";
var id = $(this).attr('data-id');
$.get(url + '/' + id, function (data) {
$('#editor-content-container').html(data);
$('#editor-container').modal('show');
});
});
});
function success(data,status,xhr) {
$('#editor-container').modal('hide');
$('#editor-content-container').html("");
}
function failure(xhr,status,error) {
$('#editor-content-container').html(xhr.responseText);
$('#editor-container').modal('show');
}
</script>
note the "editor-success-id" in data table rows.
The dataRowView
is a partial containing the presentation of an model's item.
@model ModelView
@{
var item = Model;
}
<div class="row">
// some data
<button type="button" class="btn btn-danger editor-container" data-id="@item.Id">Edit</button>
</div>
Write the partial view that is called by clicking on row's button (via JS $('.editor-container').click(function () ...
).
@model Model
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="editor-title">Title</h4>
</div>
@using (Ajax.BeginForm("MyEditAction", "Controller", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "editor-success-" + @Model.Id,
OnSuccess = "success",
OnFailure = "failure",
}))
{
@Html.ValidationSummary()
@Html.AntiForgeryToken()
@Html.HiddenFor(model => model.Id)
<div class="modal-body">
<div class="form-horizontal">
// Models input fields
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-primary">Save</button>
</div>
}
This is where magic happens: in AjaxOptions
, UpdateTargetId will replace the data row after editing, onfailure and onsuccess will control the modal.
This is, the modal will only close when editing was successful and there have been no errors, otherwise the modal will be displayed after the ajax-posting to display error messages, e.g. the validation summary.
But how to get ajaxform to know if there is an error? This is the controller part, just change response.statuscode as below in step 5:
the corresponding controller action method for the partial edit modal
[HttpGet]
public async Task<ActionResult> EditPartData(Guid? id)
{
// Find the data row and return the edit form
Model input = await db.Models.FindAsync(id);
return PartialView("EditModel", input);
}
[HttpPost, ValidateAntiForgeryToken]
public async Task<ActionResult> MyEditAction([Bind(Include =
"Id,Fields,...")] ModelView input)
{
if (TryValidateModel(input))
{
// save changes, return new data row
// status code is something in 200-range
db.Entry(input).State = EntityState.Modified;
await db.SaveChangesAsync();
return PartialView("dataRowView", (ModelView)input);
}
// set the "error status code" that will redisplay the modal
Response.StatusCode = 400;
// and return the edit form, that will be displayed as a
// modal again - including the modelstate errors!
return PartialView("EditModel", (Model)input);
}
This way, if an error occurs while editing Model data in a modal window, the error will be displayed in the modal with validationsummary methods of MVC; but if changes were committed successfully, the modified data table will be displayed and the modal window disappears.
Note: you get ajaxoptions working, you need to tell your bundles configuration to bind jquery.unobtrusive-ajax.js

In ES6, import
s are live read-only views on exported-values. As a result, when you do import a from "somemodule";
, you cannot assign to a
no matter how you declare a
in the module.
However, since imported variables are live views, they do change according to the "raw" exported variable in exports. Consider the following code (borrowed from the reference article below):
//------ lib.js ------
export let counter = 3;
export function incCounter() {
counter++;
}
//------ main1.js ------
import { counter, incCounter } from './lib';
// The imported value `counter` is live
console.log(counter); // 3
incCounter();
console.log(counter); // 4
// The imported value can’t be changed
counter++; // TypeError
As you can see, the difference really lies in lib.js
, not main1.js
.
To summarize:
import
-ed variables, no matter how you declare the corresponding variables in the module.let
-vs-const
semantics applies to the declared variable in the module.
const
, it cannot be reassigned or rebound in anywhere.let
, it can only be reassigned in the module (but not the user). If it is changed, the import
-ed variable changes accordingly.Look at Linked List as a data structure. It's mechanism to represent self-aggregation in OOD. And you may think of it as real world object (for some people it is reality)
To define the minimum value of the EditText, I used this:
if (message.trim().length() >= 1 && message.trim().length() <= 12) {
// do stuf
} else {
// Too short or too long
}
perhaps, you can first determine if the DOM does really exists,
function walkmydog() {
//when the user starts entering
var dom = document.getElementById('WallSearch');
if(dom == null){
alert('sorry, WallSearch DOM cannot be found');
return false;
}
if(dom.value.length == 0){
alert("nothing");
}
}
if (document.addEventListener){
document.addEventListener("DOMContentLoaded", walkmydog, false);
}
Something along the lines of
StringWriter errors = new StringWriter();
ex.printStackTrace(new PrintWriter(errors));
return errors.toString();
Ought to be what you need.
Relevant documentation:
strtotime('this week', time());
Replace time(). Next sunday/last monday methods won't work when the current day is sunday/monday.
I had the following problem where I was fetching data from a database and wanted to display a string containing \n
. None of the solutions above worked for me and I finally came up with a solution: https://stackoverflow.com/a/61484190/7251208
Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS
$(function() {
$("#employeeLink").on("click",function(e) {
e.preventDefault(); // cancel the link itself
$.post(this.href,function(data) {
$("#someContainer").html(data);
});
});
});
If you insist on using frames which I strongly discourage, have a form and submit it with the link
<form action="employee.action" method="post" target="myFrame" id="myForm"></form>
and use (in plain JS)
window.addEventListener("load",function() {
document.getElementById("employeeLink").addEventListener("click",function(e) {
e.preventDefault(); // cancel the link
document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
});
});
Without a form we need to make one
window.addEventListener("load",function() {
document.getElementById("employeeLink").addEventListener("click",function(e) {
e.preventDefault(); // cancel the actual link
var myForm = document.createElement("form");
myForm.action=this.href;// the href of the link
myForm.target="myFrame";
myForm.method="POST";
myForm.submit();
});
});
You can do it as follows:
> x<-c(2, 4, 6, 9, 10) # the list
> y<-c(4, 9, 10) # values to be removed
> idx = which(x %in% y ) # Positions of the values of y in x
> idx
[1] 2 4 5
> x = x[-idx] # Remove those values using their position and "-" operator
> x
[1] 2 6
Shortly
> x = x[ - which(x %in% y)]
If you receive multiple entries the correct method is called lists.
Word_relation::select('word_two')->where('word_one', $word_id)->lists('word_one')->toArray();
There's the rlist package (http://cran.r-project.org/web/packages/rlist/index.html) to deal with various kinds of list operations.
Example (http://cran.r-project.org/web/packages/rlist/vignettes/Filtering.html):
library(rlist)
devs <-
list(
p1=list(name="Ken",age=24,
interest=c("reading","music","movies"),
lang=list(r=2,csharp=4,python=3)),
p2=list(name="James",age=25,
interest=c("sports","music"),
lang=list(r=3,java=2,cpp=5)),
p3=list(name="Penny",age=24,
interest=c("movies","reading"),
lang=list(r=1,cpp=4,python=2)))
list.remove(devs, c("p1","p2"))
Results in:
# $p3
# $p3$name
# [1] "Penny"
#
# $p3$age
# [1] 24
#
# $p3$interest
# [1] "movies" "reading"
#
# $p3$lang
# $p3$lang$r
# [1] 1
#
# $p3$lang$cpp
# [1] 4
#
# $p3$lang$python
# [1] 2
Instance variables or fields, along with static variables, are assigned default values based on the variable type:
0
\u0000
or 0
0.0
false
null
Just want to clarify that local variables (ie. declared in block, eg. method, for loop, while loop, try-catch, etc.) are not initialized to default values and must be explicitly initialized.

In the comments in the answer, it does not explicitly state that nextTick shifted from Macrosemantics to Microsemantics.
before node 0.9 (when setImmediate was introduced), nextTick operated at the start of the next callstack.
since node 0.9, nextTick operates at the end of the existing callstack, whereas setImmediate is at the start of the next callstack
check out https://github.com/YuzuJS/setImmediate for tools and details
Instead of setting the value directly you can try using copy/paste, so instead of:
Worksheets(2).Cells(a, 15) = Worksheets(1).Cells(i, 3).Value
Try this:
Worksheets(1).Cells(i, 3).Copy
Worksheets(2).Cells(a, 15).PasteSpecial Paste:=xlPasteFormats
Worksheets(2).Cells(a, 15).PasteSpecial Paste:=xlPasteValues
To just set the font to bold you can keep your existing assignment and add this:
If Worksheets(1).Cells(i, 3).Font.Bold = True Then
Worksheets(2).Cells(a, 15).Font.Bold = True
End If
Some quick tips:
This happens when you index a row/column with a number that is larger than the dimensions of your dataframe
. For instance, getting the eleventh column when you have only three.
import pandas as pd
df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})
You have 5 rows and three columns:
Name City Car
0 Mark Lisbon Tesla
1 Laura Montreal Audi
2 Adam Lisbon Porsche
3 Roger Berlin Ford
4 Anna Glasgow Honda
Let's try to index the eleventh column (it doesn't exist):
df.iloc[:, 10] # there is obviously no 11th column
IndexError: single positional indexer is out-of-bounds
If you are a beginner with Python, remember that df.iloc[:, 10]
would refer to the eleventh column.
num=35; num.replace(3,'three'); =====> ERROR
num=35; num.toString().replace(3,'three'); =====> CORRECT !!!!!!
num='35'; num.replace(3,'three'); =====> CORRECT !!!!!!
You just add an accessor who define what you change
class Post < AR::Base
attr_reader :what_changed
before_filter :what_changed?
def what_changed?
@what_changed = changes || []
end
after_filter :action_on_changes
def action_on_changes
@what_changed.each do |change|
p change
end
end
end
Nowadays, considering such compilers as Intel C++ which extremely optimizing C code, it is very hard to compete with compilers output.
In my case JAVA path was not set in Env variables. Started to work after correct path was set in Env PATH.
Type javac in command prompt and make sure JAVA PATH is correct.
Just recreate the Path variable in users. Go to user variables, highlight path, then new, the type in value. Look on another computer with same version windows. Usually it is in windows 10: Path %USERPROFILE%\AppData\Local\Microsoft\WindowsApps;
The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.
import numpy as np
names = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 , 0.5678 , 0.9123 ])
ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats
np.savetxt('test.txt', ab, fmt="%10s %10.3f")
Update: This example also works properly in Python 3 by using the 'U6'
Unicode string dtype, when creating the ab
structured array, instead of the 'S6'
byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1'
in Python 3.
There is a helper library for this.
Swift 5

Swift 4.0 - Swift 4.2
pod 'DeviceKit', '~> 1.3'
if you just want to determine the model and make something accordingly.
You can use like that :
let isIphoneX = Device().isOneOf([.iPhoneX, .simulator(.iPhoneX)])
In a function :
func isItIPhoneX() -> Bool {
let device = Device()
let check = device.isOneOf([.iPhoneX, .iPhoneXr , .iPhoneXs , .iPhoneXsMax ,
.simulator(.iPhoneX), .simulator(.iPhoneXr) , .simulator(.iPhoneXs) , .simulator(.iPhoneXsMax) ])
return check
}
Override the handleIntent
Method of the FirebaseMessageService
works for me.
here the code in C# (Xamarin)
public override void HandleIntent(Intent intent)
{
try
{
if (intent.Extras != null)
{
var builder = new RemoteMessage.Builder("MyFirebaseMessagingService");
foreach (string key in intent.Extras.KeySet())
{
builder.AddData(key, intent.Extras.Get(key).ToString());
}
this.OnMessageReceived(builder.Build());
}
else
{
base.HandleIntent(intent);
}
}
catch (Exception)
{
base.HandleIntent(intent);
}
}
and thats the Code in Java
public void handleIntent(Intent intent)
{
try
{
if (intent.getExtras() != null)
{
RemoteMessage.Builder builder = new RemoteMessage.Builder("MyFirebaseMessagingService");
for (String key : intent.getExtras().keySet())
{
builder.addData(key, intent.getExtras().get(key).toString());
}
onMessageReceived(builder.build());
}
else
{
super.handleIntent(intent);
}
}
catch (Exception e)
{
super.handleIntent(intent);
}
}
When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools
If customer primary contact medium is email, if email is null then phonenumber, and if phonenumber is also null then address. It would be written using COALESCE as
coalesce(email,phonenumber,address)
while the same in hive can be achieved by chaining together nvl as
nvl(email,nvl(phonenumber,nvl(address,'n/a')))
No behaviors can be set by CSS. The only way to disable something in CSS is to make it invisible by either setting display:none
or simply putting div with transparent img all over it and changing their z-orders to disable user focusing on it with mouse. Even though, user will still be able to focus with tab from another field.
You can just use localStorage
and remember the date it was first created in session cookie
. When localStorage
"session" is older than the value of cookie then you may clear the localStorage
Cons of this is that someone can still read the data after the browser is closed so it's not a good solution if your data is private and confidental.
You can store your data to localStorage
for a couple of seconds and add event listener for a storage
event. This way you will know when any of the tabs wrote something to the localStorage
and you can copy its content to the sessionStorage
, then just clear the localStorage

ARIA (Accessible Rich Internet Applications) defines a way to make Web content and Web applications more accessible to people with disabilities.
The hidden
attribute is new in HTML5 and tells browsers not to display the element. The aria-hidden
property tells screen-readers if they should ignore the element. Have a look at the w3 docs for more details:

FYI: g++ offers the non-standard __PRETTY_FUNCTION__ macro. Until just now I did not know about C99 __func__ (thanks Evan!). I think I still prefer __PRETTY_FUNCTION__ when it's available for the extra class scoping.
PS:
static string getScopedClassMethod( string thePrettyFunction )
{
size_t index = thePrettyFunction . find( "(" );
if ( index == string::npos )
return thePrettyFunction; /* Degenerate case */
thePrettyFunction . erase( index );
index = thePrettyFunction . rfind( " " );
if ( index == string::npos )
return thePrettyFunction; /* Degenerate case */
thePrettyFunction . erase( 0, index + 1 );
return thePrettyFunction; /* The scoped class name. */
}
I`d like to add to the already good answers:
The symbols '+', '*' and '-' are sometimes used as shorthand in some older textbooks for OR,? and AND,? and NOT,¬ logical operators in Bool`s algebra. In C/C++ of course we use "and","&&" and "or","||" and "not","!".
Watch out: "true + true" evaluates to 2 in C/C++ via internal representation of true and false as 1 and 0, and the implicit cast to int!
int main ()
{
std::cout << "true - true = " << true - true << std::endl;
// This can be used as signum function:
// "(x > 0) - (x < 0)" evaluates to +1 or -1 for numbers.
std::cout << "true - false = " << true - false << std::endl;
std::cout << "false - true = " << false - true << std::endl;
std::cout << "false - false = " << false - false << std::endl << std::endl;
std::cout << "true + true = " << true + true << std::endl;
std::cout << "true + false = " << true + false << std::endl;
std::cout << "false + true = " << false + true << std::endl;
std::cout << "false + false = " << false + false << std::endl << std::endl;
std::cout << "true * true = " << true * true << std::endl;
std::cout << "true * false = " << true * false << std::endl;
std::cout << "false * true = " << false * true << std::endl;
std::cout << "false * false = " << false * false << std::endl << std::endl;
std::cout << "true / true = " << true / true << std::endl;
// std::cout << true / false << std::endl; ///-Wdiv-by-zero
std::cout << "false / true = " << false / true << std::endl << std::endl;
// std::cout << false / false << std::endl << std::endl; ///-Wdiv-by-zero
std::cout << "(true || true) = " << (true || true) << std::endl;
std::cout << "(true || false) = " << (true || false) << std::endl;
std::cout << "(false || true) = " << (false || true) << std::endl;
std::cout << "(false || false) = " << (false || false) << std::endl << std::endl;
std::cout << "(true && true) = " << (true && true) << std::endl;
std::cout << "(true && false) = " << (true && false) << std::endl;
std::cout << "(false && true) = " << (false && true) << std::endl;
std::cout << "(false && false) = " << (false && false) << std::endl << std::endl;
}
yields :
true - true = 0
true - false = 1
false - true = -1
false - false = 0
true + true = 2
true + false = 1
false + true = 1
false + false = 0
true * true = 1
true * false = 0
false * true = 0
false * false = 0
true / true = 1
false / true = 0
(true || true) = 1
(true || false) = 1
(false || true) = 1
(false || false) = 0
(true && true) = 1
(true && false) = 0
(false && true) = 0
(false && false) = 0
newTitle
is a local variable where you create the fields. So when that functions ends, the variable newTitle
, does not exist anymore. (The JTextField that was referenced by newTitle
does still exist however.)
Thus, increase the scope of the variable, so that you can access it another method.
public SomeFrame extends JFrame {
JTextField myTitle;//can be used anywhere in this class
creationOfTheFields()
{
//other code
myTitle = new JTextField("spam");
myTitle.setBounds(80, 40, 225, 20);
options.add(myTitle);
//blabla other code
}
private void New_Name()
{
this.setTitle(myTitle.getText());
}
}
For fibonacci recursive solution, it is important to save the output of smaller fibonacci numbers, while retrieving the value of larger number. This is called "Memoizing".
Here is a code that use memoizing the smaller fibonacci values, while retrieving larger fibonacci number. This code is efficient and doesn't make multiple requests of same function.
import java.util.HashMap;
public class Fibonacci {
private HashMap<Integer, Integer> map;
public Fibonacci() {
map = new HashMap<>();
}
public int findFibonacciValue(int number) {
if (number == 0 || number == 1) {
return number;
}
else if (map.containsKey(number)) {
return map.get(number);
}
else {
int fibonacciValue = findFibonacciValue(number - 2) + findFibonacciValue(number - 1);
map.put(number, fibonacciValue);
return fibonacciValue;
}
}
}
Just for other people's benefit. If the error is a 401.1 Unauthorized
and your error code matches 0xc000006d

The work around is a registry hack that disables this policy explicitly.
To perform this configuration manually find this key in the registry on the server:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
and edit or add a new key:
DisableLoopbackCheck
(DWORD)then sent the value to 1 to disable the loopback check (local authentication works), or to 0 (local authentication is not allowed).
Or more easily you can use Powershell:
New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa -Name "DisableLoopbackCheck" -Value "1" -PropertyType dword
It looks like recent builds of Windows 10 (1803 and later?) also require this configuration setting in order to authenticate locally.
This one took me awhile because everyone else's comments here failed to help me. I found this article and it fixed it!
An image is to a class as a container to an object.

The accepted solution of modifying a Run Configuration wasn't ideal for me as I have a few different run configurations and could easily forget to do this when adding further ones in future. Also I wanted the setting to apply whenever running anything, e.g. when running JUnit tests by right-clicking and selecting "Run As" -> "JUnit Test".
The above can be achieved by modifying the JRE/JDK settings instead:-
-Xms512m -Xmx4G -XX:MaxPermSize=256M
You should use the OpenFileDialog class like this
Dim fd As OpenFileDialog = New OpenFileDialog()
Dim strFileName As String
fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True
If fd.ShowDialog() = DialogResult.OK Then
strFileName = fd.FileName
End If
Then you can use the File class.
Exported variables such as $HOME
and $PATH
are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.
$ env | grep '^variable='
$ # No environment variable called variable
$ variable=Hello # Create local (non-exported) variable with value
$ env | grep '^variable='
$ # Still no environment variable called variable
$ export variable # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$
For more information, see the entry for the export
builtin in the GNU Bash manual, and also the sections on command execution environment and environment.
Note that non-exported variables will be available to subshells run via ( ... )
and similar notations because those subshells are direct clones of the main shell:
$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$
The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.
Some information about subshells can be found under command grouping and command execution environment in the Bash manual.
DO NOT put ALTER TABLE/MODIFY COLS or any other such table mod operations inside a TRANSACTION. Transactions are for being able to roll back a QUERY failure not for ALTERations...it will error out every time in a transaction.
Just run a SELECT * query on the table and check if the column is there...
yield is similar to return. The difference is:
yield makes a function iterable (in the following example primes(n = 1)
function becomes iterable).
What it essentially means is the next time the function is called, it will continue from where it left (which is after the line of yield expression
).
def isprime(n):
if n == 1:
return False
for x in range(2, n):
if n % x == 0:
return False
else:
return True
def primes(n = 1):
while(True):
if isprime(n): yield n
n += 1
for n in primes():
if n > 100: break
print(n)
In the above example if isprime(n)
is true it will return the prime number. In the next iteration it will continue from the next line
n += 1
string text = "ABCD";
for (int i = 0; i < text.Length; i++)
{
Console.WriteLine(text[i] + " => " + Char.ConvertToUtf32(text, i));
}
If I remember correctly, the ASCII value is the number of the lower seven bits of the Unicode number.
No, you cannot modify it, as the string can be stored in read-only memory. If you want to modify it, you can use an array instead e.g.
char a[] = "This is a string";
Or alternately, you could allocate memory using malloc e.g.
char *a = malloc(100);
strcpy(a, "This is a string");
free(a); // deallocate memory once you've done
Lodash has a "map" function that works just like jQuerys:
var myArr = [{ name: "john", age:23 },_x000D_
{ name: "john", age:43 },_x000D_
{ name: "jimi", age:10 },_x000D_
{ name: "bobi", age:67 }];_x000D_
_x000D_
var johns = _.map(myArr, function(o) {_x000D_
if (o.name == "john") return o;_x000D_
});_x000D_
_x000D_
// Remove undefines from the array_x000D_
johns = _.without(johns, undefined)
_x000D_
You will need to set the permissions every time you plug the converter in. I use PuTTY to connect. In order to do so, I have created a little Bash script to sort out the permissions and launch PuTTY:
#!/bin/bash
sudo chmod 666 /dev/ttyUSB0
putty
P.S. I would never recommend that permissions are set to 777.

This is what you can do to source an .env (and .flaskenv) file in the pycharm flask/django console. It would also work for a normal python console of course.
Do pip install python-dotenv
in your environment (the same as being pointed to by pycharm).
Go to: Settings > Build ,Execution, Deployment > Console > Flask/django Console
In "starting script" include something like this near the top:
from dotenv import load_dotenv load_dotenv(verbose=True)
The .env file can look like this:
export KEY=VALUE
It doesn't matter if one includes export
or not for dotenv to read it.
As an alternative you could also source the .env file in the activate shell script for the respective virtual environement.

Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageUrl).getContent());
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
If you need to do transformations on the image, you'll want to create a Drawable instead of a Bitmap.
Even i had the same problem ,finally understand my issue , i was trying to connect from (out of range) Bluetooth coverage range.

You need to use a ServerSocket
. You can find an explanation here.
1) Update conda
Run the anaconda prompt as administrator
conda update -n base -c defaults conda
2) Create an environment for python new version say, 3.6
conda create --name py36 python=3.6
3) Activate the new environment
conda activate py36
4) Upgrade pip
pip install --upgrade pip
5) Install tensorflow
pip install https://testpypi.python.org/packages/db/d2/876b5eedda1f81d5b5734277a155fa0894d394a7f55efa9946a818ad1190/tensorflow-0.12.1-cp36-cp36m-win_amd64.whl
If it doesn't work
If you have problem with wheel at the environment location, or pywrap_tensorflow problem,
pip install tensorflow --upgrade --force-reinstall

*(myString.end() - 1)
maybe? That's not exactly elegant either.
A python-esque myString.at(-1)
would be asking too much of an already-bloated class.

In my case I wanted to use a Swift protocol in an Objective-C header file that comes from the same target and for this I needed to use a forward declaration of the Swift protocol to reference it in the Objective-C interface. The same should be valid for using a Swift class in an Objective-C header file. To use forward declaration see the following example from the docs at Include Swift Classes in Objective-C Headers Using Forward Declarations:
// MyObjcClass.h
@class MySwiftClass; // class forward declaration
@protocol MySwiftProtocol; // protocol forward declaration
@interface MyObjcClass : NSObject
- (MySwiftClass *)returnSwiftClassInstance;
- (id <MySwiftProtocol>)returnInstanceAdoptingSwiftProtocol;
// ...
@end

Try this, add these lines to your edit text view, i'll add mine. make sure you understand it
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
<EditText
android:inputType="textMultiLine"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/editText_newprom_description"
android:padding="10dp"
android:lines="5"
android:overScrollMode="always"
android:scrollbarStyle="insideInset"
android:minLines="5"
android:gravity="top|left"
android:scrollbars="vertical"
android:layout_marginBottom="20dp"/>
and on your java class make on click listner to this edit text as follows, i'll add mine, chane names according to yours.
EditText description;
description = (EditText)findViewById(R.id.editText_newprom_description);
description.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK){
case MotionEvent.ACTION_UP:
view.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
return false;
}
});
this works fine for me
Normally Python throws NameError
if the variable is not defined:
>>> d[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined
However, you've managed to stumble upon a name that already exists in Python.
Because dict
is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.
The type of dict
is a type
. All types are objects in Python. Thus you are actually trying to index into the type
object. This is why the error message says that the "'type' object is not subscriptable."
>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable
Note that you can blindly assign to the dict
name, but you really don't want to do that. It's just going to cause you problems later.
>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'
The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:
d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))
Well I found this way :
Oracle SQL Developer (Left top icon) > Preferences > Database > NLS and set the Date Format as MM/DD/YYYY HH24:MI:SS
I am using Horizonal Recyclerview.
1) Here in CardView, TextView gets distorted vertically when using
android:ellipsize="end"
android:maxLines="1"
Check the bold TextViews Wyman Group, Jaskolski...
2) But when I used singleLine along with ellipsize -
android:ellipsize="end"
android:singleLine="true"
Check the bold TextViews Wyman Group, Jaskolski...
2nd solution worked for me properly (using singleLine). Also I have tested in OS version: 4.1 and above (till 8.0), it's working fine without any crashes.
